Femoral artery puncture postoperative pressing system

Abstract

A femoral artery puncture postoperative pressing system comprises a fixing plate arranged above one side of a flat plate for a patient to lie on his or her back and a lifting baseplate arranged belowthe fixing plate through a lifting cylinder. The lifting baseplate is connected with a piston rod of the lifting oil cylinder to adjust an interval between the lifting baseplate and the upper surfaceof the flat plate through extension and contraction of the piston rod of the lifting hydraulic oil cylinder, and a puncture port pressing device is arranged on the lifting baseplate. A pressing head has a semispherical pressing face which can well fit physiological structure at the root of a thigh and synchronously press a puncture point and range around the puncture point, so that pressing effectis improved, and shifting of a pressing position due to body moving can be prevented; by arranging a cold compress assisting mechanism in front of the pressing head, cold air generated after gas passes an ice storage chamber is utilized to cool a cold compress metal belt to enable flowing speed of blood in skin enveloped by the cold compress metal belt under stimulation of the cold air to be lowered, so that pressing time is shortened.

Description

technical field [0001] The invention relates to a femoral artery puncture surgical instrument in the field of medical instruments, in particular to a pressing system after femoral artery puncture. Background technique [0002] Femoral artery puncture is a surgical operation, mainly for the following purposes: 1. Collect arterial blood samples or some special examinations; 2. Pressurized blood transfusion in emergency; 3. Used for regional chemotherapy; in addition, In the treatment of cardiovascular diseases, such as cardiac interventional surgery, femoral artery puncture is also required. [0003] After the puncture of the femoral artery is completed, the puncture point needs to be pressed to facilitate hemostasis and healing of the puncture port. Existing pressing methods are generally divided into manual pressing by medical personnel and simple mechanical pressing with the help of machinery. Although manual pressing has achieved certain effects, it consumes more manpower...

AI Technical Summary

Problems solved by technology

[0005] For example, the utility model patent with application number 2018200567044 discloses a device for pressing the puncture site after cardiovascular intervention. Although this pressing device solves the problem of using mechanical force instead of manual pressing, because the arc-shaped limiting plate is used to press the puncture port, and when the femoral artery is punctured, the puncture point is located at the root of the thigh. Due to the special structure of the human thigh As a result, the effect of this pressing method is not ideal;

[0006] As another example, the utility model patent with application number 2016201567555 also discloses a device for pressing the puncture site after cardiovascular intervention. This device also uses a telescopic rod to drive a slider to adjust the height. Hold the cotton ball to press the puncture site; the problem in this patent is that the area of ​​the puncture site held by the claws holding the cotton ball to press the puncture site is small, and there is no effective fixation of the patient's body. Once the patient moves abnormally, it will cause The deviation of the pressing part, the pressing effect is not ideal in practical application;

[0007] In addition, the utility model patent with application number 992046076 discloses a presser for cardiovascular imaging. The core of this patent is to use the pressurized screw to drive the pressure plate to press the puncture site; question
